PRODUCT FEATURE A 17 to 27 GHz GaAs MMIC Gain Block Amplifier from Multiple Sources Mimix Broadband Webster, TX A GaAs MMIC three-stage gain block amplifier covering the 17 to 27 GHz frequency range has been developed that features the option of individually biasing the three stages or biasing...

TECHNICAL FEATURE Finite Element Determination of the Intrinsic Small-signal Equivalent Circuit of MESFETs The finite element time domain method is used to determine the intrinsic elements of a broadband, small-signal equivalent circuit (SSEC) of FETs. The values of the different elements are calculated from the Y parameters of the...

TECHNICAL FEATURE A Method of Measuring Large-signal S-parameters of High Power Transistors A measurement method for scattering parameters (S-parameters) of high power transistors is presented. The proposed method directly determines the S-parameters of high power transistors by measuring overall gain, phase and S-parameters of input and output matching network...

TECHNICAL FEATURE Design of a Planar Microstrip Balun at S-band An innovation for the Marchand balun model is presented. The structure of the designed planar microstrip matching circuit is fairly simple, practical and easily fabricated without requiring complex multiple metal or dielectric layers. Moreover, the designed balun performs well....

TECHNICAL FEATURE Two Novel Radar Vehicle Detectors for the Replacement of a Conventional Loop Detector In this article, intrusive and non-intrusive radar vehicle detectors, compatible with existing inductive loop detectors (ILD) without any modification of the communication algorithm, have been developed at 24 GHz. The intrusive detector is based...

TECHNICAL FEATURE Complex Coaxial-waveguide Transitions at Millimeter-waves Millimeter-waves have been used in commercial applications during the last decade as a result of the growing development of microwave multipoint distribution systems, local multipoint distribution systems, and digital audio and video broadcasting. In spite of many proposed simulation methods, experimentation remains...
